1. Install two SAN256N chassis support brackets (5416871-201) onto the inside rails of
the SANC40 cabinet. The support brackets are positioned so that a 3.5 inch opening
exists between the top of the existing SAN256N chassis and the bottom of the (to be
installed) SAN256N chassis.
2. Verify the positioning of the SAN256N chassis mounting brackets on the sides of the
chassis. For a SANC40 cabinet installation, the mounting bracket ears are positioned
toward the rear of the SAN256N chassis. If the brackets are not installed in this
orientation, unscrew the four sets of mounting hardware on each bracket, then
remove, reverse and remount the brackets to the chassis.

3. Tilt the chassis upward from the packing skid, high enough to allow the blades of the
lifting device to slide underneath the bottom of the chassis as the blades are inserted
from the front side of chassis.
4. Carefully position the chassis on the blades; raise the blades to a safe and
comfortable height for transporting chassis to the designated cabinet for installation.
5. Transport the chassis to the front side of the cabinet.
6. Position the lifting device in front of the cabinet so that the chassis is horizontal and
elevated slightly above the chassis support brackets installed earlier.
7. Carefully slide the chassis onto the chassis support brackets until the left and right
SAN256N chassis mounting brackets are tight against the cabinet’s mounting rails.
8. Carefully lower the blades from underneath the chassis and remove the lifting device
from the cabinet.
9. Insert eight 10/32 x 3/8 PPH screws and #10 washers, through the bracket mounting
holes. Tighten the screws to secure the brackets/chassis to the cabinet rails.
